I recently began using a GFO reactor to help in keeping my walls and LR clean of algae. What I like about the granular GFO is that it tumbles well in the reactor and being small granules it has huge amounts of surface space to absorb through. I've been running it for several weeks now and have noticed much improvement in my algae issues.

I defiantly recommend granular GFO!

Keeps phosphates at 0 and that's where it needs to be. I use this product in dual reactor chambers and I do use a lot.

with the BRS reactor, this GFO is not only affordable, it does a great job. I originally purhased this when I had a dyno outbreak, which went away! But now its just part of my system. I use 2TSP per 4 gallons of water, change about once a month.

Works goodBy ReefKrazyon 9/1/2010

ReefKrazy would recommend this product to a friend

Works good lowered my PO4 in a single night I would recommend using this but I feel that the HC GFO would be better because you can treat a larger water volume in the same size reactor cartridge and can still leave a little room for tumbling. Plan on having some water made up for rinsing.

Great product.By Billon 8/30/2010

Have yet to get a reading other then zero from a phosphate test since i started using this product. Very low dust, once flow is set through reactor dont have to mess with and it never clumps.

Truly A MustBy Michaelangeloon 7/20/2010

Few things in Reefing I live by and GFO is one! It cuts my phosphates to 0 using my Hannah Phosphate reader! This is a great buy if your using a reactor because not only are you getting a great price but the Reef Calculator on the homepage tells you exactly how much to use. I do wish however it came with a measuring tool.

This stuff is great! When I first started this my phosphate levels were above 1.0. After a few weeks I was way down in the point .1s. Now I do it regularly and only have to replace the media every 5 weeks in the dual reactor.

I just wanted to share that one thing i love about this product is is alot drier than the phosloc brand so it tumbles alot better in my reactor and does not require as much force from the pump. Also works great at removing phosphates i know when to change it because algae starts growing on my glass again. :)

Great product and no difference between this and higher priced products. It does create some dust but all GFP products do. I do not even bother checking my phosphates. All I know is I do not have unwanted algae growth.

I was having problems with algae outbreaks even with using RO water etc. After about 2 weeks of use with this product the algae has subsided and my clean up team is able to keep up with it again. Easy to use with the BRS dosing guide. I use in filter bag in sump with power head circulating water to it.

One of the better ways to remove excess phosphates from your reef aquarium. I was having some serious cyano and hair algae problems and within probably a month of using this product, they were gone. I also didn't do h2o changes and kept the same husbandry to see if it actually was this and I'd have to say that it was.

This is a great product at a reasonable price. I started using it on my 90g reef tank, and it did a fantastic job of eliminating my phosphate problem. I will continue to use this product on a continuos basis.

Excellent ProductBy flancon 2/17/2010

This product performs well and has minimal dust. Care must be used when setting up flow rates through the reactor. Too fast and it will grind it self up and too slow and it will settle to a fused lump. With a little practice very easy to setup and run.

I have bought many types of GFO through the years, at varying prices. The bottom line on this product is that it is affordable if bought in bulk. Further, it is clean. Not a lot of dust. Recommended.

I have a smaller system , 80 gallon with 40 gallon sump/refugium- I use it in a BRS 4X8 mesh bag- I rinse it 3X in RO/DI (about 1/3 gallon each time)- just takes a few minutes- then place the bag in the return flow in the sump. I change it every 2 weeks. Works great.

No question this material works well. Use it in one of the reactors offered here and adjust the flow as instructed. It last longer and worked faster than I expected after using other brands.

Phosphate Blaster.....By Deep Blue Seaon 12/22/2009

Deep Blue Sea would recommend this product to a friend

I use this product in a large media reactor (1000 gal+ system) sandwiched between two layers of carbon so that it doesn't escape through the top of the reactor. It brought down and continues to maintain phosphate levels at or near zero. Once the loaded up media reactor is ready to go, it is imperative to send initial exit water out into the sink/sewer and not into the tank until the water runs clear for a couple of minutes. Works like a charm.

It is also a good idea to load up your media reactor in a well ventilated place (ideally outside) as there is quite a bit of rust dust that becomes airborne when used in large qtys.

This is so much more cost effective than purchasing GFO from anywhere else I could find. I believe the GFO pellets are the way to go and they do a great job keeping phospate in check.

I purchased this product along with the ROX.8 Carbon to use in the Dual BRS GFO and Carbon reactor. What an incredible solution to my phosphate problem! It has reduced the phosphates to below my test kits ability to measure. It's great. I don't have any problems with it causing any dust in the tank at all. It's great and I keep using it constantly in my sump.
